I applied online. I interviewed at ION Group (Gurgaon, Haryana)
Interview
The initial interview process was in 2 parts: technical and case study.
The technical part contained a few questions based on my resume and a few behavioral questions (may vary depending on the interviewer), and if you pass that, you head on to the case study part. The case study part can be solved if you use your common sense and creativity. Overall, it was a decent process.
